2 This factory applied, ACTIVE corrosion protection system, will extend the service life of your pipeline and reduce on-site handling by eliminating the requirement for polyethylene ZINC/ALUMINIUM ALLOYThe entire outer surface of the ductile iron pipe is coated in an 85% zinc and 15% aluminium alloy at a density of 400g per m2. This hot metal spray is applied directly onto the ductile iron providing active galvanic PAM patented ZnAl alloy applied at twice the density of standard zinc LAYER OF ZINC-ALUMINIUM 85/15 ALLOY WITH A MINIMUM DENSITY OF 400g/m2A PROTECTIVE LAYER OF SYNTHETIC RESIN 100 mDUCTILE IRON2 ZINALIUM ACTIVE CORROSION PROTECTIONPORE SEALERZnAl ALLOYDUCTILE IRONZnAlIMPROVING EFFICIENCIES WITH FASTER, EASIER DI pipe INSTALLATIONZINALIUM ACTIVE CORROSION PROTECTION 3 The factory applied, ACTIVE corrosion protection system removes the risks associated with installation of sleeving, as it is no longer required.

3 In addition, Zinalium will ACTIVELY protect the underlying iron against scratches and scrapes which can commonly occur during transport and , EASIER INSTALLATIONE xtensive research in the installation of loose polyethylene sleeving reveals that it takes up to 15 minutes per length of pipe to install. This accumulated time can account for up to 5% of the cost of a pipeline, tying up personnel and eliminating the need for sleeving, the installation of Ductile Iron pipe becomes a simple one step push fit operation. ALUMINIUM, WORKING WITH ZINCThe perfect combination of aluminium and zinc in the ZnAl alloy considerably increases the strength of the protective properties of the outer high quality zinc hydroxide layer can only form when the zinc transforms at an appropriate rate.

4 In Zinalium , this change is optimised by two factors:- the porous paint layer is applied at an optimum thickness to allow both the formation of zinc hydroxides and the ongoing galvanic effect;- the presence of aluminium slows the transformation effect to allow the creation of a more stable protective layer compared to zinc alone, whilst allowing the sacrificial galvanic healing process to take COSTNot only will contractors find a typical ~5% cost saving in time, but also further saving in the cost of the sleeving itself which makes up to 2% of the cost of Ductile Iron pipe as a complete end result is a cost effective solution which will increase installation efficiency and asset life.

5 THE ACTIVE PROPERTIES OF ZINCThe Zinalium coating system benefits from the 'active' properties of the Zinc-Aluminium alloy when in contact with the soil in that it:- provides a long term barrier by forming a stable all-round protective layer (zinc hydroxides) covering the entire surface of the buried pipe ;- restores the protective layer at points where it has been slightly damaged (impacts during transportation, scrapes when backfilling) through the galvanic effect between the exposed iron and the zinc around the coated in PAM s patented Zinalium alloy may be buried in contact with the majority of soils, except:- Acidic peaty soils;- Soils below the marine water table with a resistivity lower than 500 delivers savings in installation time and overall TYTONHYDROCLASS ZINALIUM SYSTEMLINING OPTIONSHYDROLINE-C is a centrifugally spun cement mortar lining made up of Type SR (Sulphate Resisting) Blast Furnace Slag cement standard internal is HYDROLINE-C with an added Seal Coat to inhibit the leaching of lime where very aggressive, soft waters of low hardness (total alkalinity <30mg/L) or high dissolved C02 are being conveyedTECHNICAL DATAS izes DN 100 - DN 750 Certification TYTONHYDROCLASS pipes are certified to.
